It is important to point out that, at high energies, the DVCS cross section at the
photon level is dominated by the contribution of the transversely polarized
virtual photons due to the helicity conservation [1]}.
In the language of the color dipole model,
this dominance is explained by the dominance of the large transverse-size dipoles
over the small transverse-size dipoles, see [2]} for the discussion.
Therefore, Eq. (REF ) gives the complete description of the DVCS
amplitude.
